How can Baltimore become safer?
Improve schools
- Easier said than done
- Often controversial (NCLB, school choice)
- Can throw money at it, but taxes are already high
Improve the local economy

Reduce drug use (and trade, etc.)
- “Heroin capital of North America”
- Clear as day throughout city
Get guns off of the streets

Improve policing

Cameras
Baltimore Police CCTV

Johns Hopkins CCTV
- 1500 cameras on East Baltimore campus (?)
- Problems according to George Economas:
- Lenses gets wet/dirty
- Storing video
- Poor resolution
Idea: Crowdsourced CCTV
Technical points
- R packages
- shiny, rtweet, mapview, sp
- Videos stored on YouTube
- Data is lightweight (YouTube URL + time of tweet + lat/long)
Some initial concerns
- Data usage
- Battery
- Using phone while recording
Why I’m excited about it
- Free, immediate, non-governmental solution
